We’re suppose to lift with our legs, but whats makes our back not suitable for it. Silly question i know.
In: Biology
When you lift with your back, you put a lot of pressure on all the joints of your spine, causing damage.
Imagine it like a long stack of connected legos. If you put pressure on the middle (which represents bending and lifting) it is more likely to fall appart than if you have a smaller stack of blocks (think of a 1×10 stack as your back vs 2×4 stack as your legs).
